TheGuardian.com reports that Brandao will be disciplined for his actions against Thiago Motta:

The Bastia striker Brandao has been provisionally suspended until 18 September by the disciplinary committee of the Ligue de Football Professionnel and could yet face further action over his headbutt on Paris Saint-Germain’s Thiago Motta.

Motta will not need a face mask to face Evian this weekend, despite the PSG star's recent altercation with Bastia striker Brandao.

I want to know how many will match ban this guy … an unfair guy all the time !! Who wants to talk all the time instead of playing !! If I took 3 three games there 2 years for touching the referee … Imagine aggression like that !!! The fourth official has seen it all, I was at his side when the guy attacked our player.

Original Text

Paris Saint-Germain midfielder Thiago Motta and Bastia striker Brandao were reportedly involved in an altercation in the tunnel following Saturday's Ligue 1 match. The incident left the PSG star with facial injuries.

Jonathan Johnson of ESPNFC reports the scrap broke out shortly after the Parisians completed a 2-0 victory with numerous onlookers:

James Horncastle of BT Sport provided a picture following the altercation which shows Motta with blood dripping from his nose:

RMC Sport passed along video of the chaos, which seemingly shows a headbutt and then a large scuffle outside of the locker room:

Here's a zoomed-in view of the moment of impact from Tom Williams of the Agence France-Presse:

It's unclear exactly what sparked the madness.

Brandao was clearly waiting for Motta to come off the pitch and confronted him immediately before delivering the headbutt and running off. A large group of players and other personnel were forced to calm the situation.

Ligue 1 and the French Football Federation will likely look into the incident. It definitely wouldn't be a surprise to see a ban handed out to Brandao for attacking an opposing player following a match, but more details will need to get gathered first.

Peter McVitie of Goal.com later provided an additional statement from Al-Khelaifi discussing the incident with reporters:

This is very serious. We cannot let this go. It gives a very bad image of football.

I hope the Bastia player who did it will be severely punished. A landmark decision needs to be made and a heavy penalty handed out.

Our role is to protect the players, and when Thiago Motta is attacked like this, we must act to counter that.

Thiago has a broken nose and will miss four games. Everyone saw what happened. The images confirm this and there will inevitably be sanctions. We hope so. It spoils the game.

Also important to Paris Saint-Germain is the status of Motta. They had already lost star striker Zlatan Ibrahimovic to an apparent hip injury, as per Fox Soccer, during the match. Another key injury isn't the way the defending champions wanted to start the campaign.

More information will be provided as it becomes available, but the video points toward serious disciplinary action for Brandao.
